the rear fork members C, is connected at its rear end with the outer end of the spiudleD, and at its forward end with the crank bracket F. It therefore passes diagonally through the case, and the meeting edges of the case sections are notched at a and a to permit it to so pass. The notches a a are of such depth that when the case is closed, it fits closely against the fork member C. The case thus rests upon, and. is supported by, the fork member in the proper relation to the driving mechanism.

It is very desirable to have some means by which the chain may be oiled without removing the case. I therefore secure to the upper edge of the section Aan oil cup E, which is adapted to discharge into the case. Supported in the case just below the discharge orifice of the oil cup, is a piece of wicking C, which rests upon the upper side of the chain H. The oil drops from the oil cup onto the wicking, from which it is delivered to the chain. The cup is provided with an automatically operating valve, whereby a limited quantity of oil is delivered to the wicking when the bicycle is in use. In the cup is a ball (2, which is adapted to close the discharge orifice. A light coil spring 6 is secured to the cover of the cup, and when the cover 1s in place, the lower end of the spring engages with the ball and presses it to its seat. But when the bicycle is being ridden, the vibration will jar the ball slightly from its seat, and thus sufficient oil will be permitted to escape for the intended purpose,

Having described my invention, I claim- 1. In a bicycle, the combination of a gearcase adapted to inclose the two sprocket wheels and the driving chain, with one of the rear fork memberswhich passes diagonally through said case, and suitable means for clamping said fork member on both sides of the case, whereby the latter is supported, substantially as specified.

2. In a bicycle, a gear case adapted to inclose the two sprocket wheels and driving chain, composed of two substantially equal longitudinal sections which are hinged together at one end, the meeting edges of said sections being notched substantially as described, to permit the crank shaftand the rear wheel hub and spindle, and one of the rear fork members to pass through the case when the same is closed, combined with said rear fork member, which passes diagonally through the case and upon which the ease rests, and means for securing together the free ends of the ease sections, substantially as set forth.

In testimony whereof Iaffix my signature in presence of two witnesses.
